The Intel Core i7 8700Ok CPU is our first actual style of the brand new Coffee Lake structure. Despite the myriad rumours, hypothesis, and leaked evaluations, it’s nonetheless a captivating processor launch. That, nonetheless, is extra due to what it represents than how the precise silicon in query performs.
The CPU is nothing in a gaming rig with no good GPU, so right here’s our decide of the best graphics cards to pair together with your processor.
This is the primary related processor launch since AMD received again into the CPU recreation with their Ryzen chips again in March. Of course, we’ve had the mine’s-bigger-than-yours playground scuffle between the ultra-enthusiast (learn: willy-waving) server-derived Threadripper and Core X elements, however they characterize such a tiny share of the processors us regular people will purchase that they’re basically supercar-like chips for the super-rich.
Well, besides the poor li’l hexcore i7 7800X. That’s turned out to be extra like a kit-car, with the physique of a Lamborghini Countach and the engine of a Mini Metro, as a result of this sizzling new Intel hatchback chip has received it beat on the drag strip lower than three months after launch.
Pricing goes to be fascinating for this one, with Intel claiming a $359 (£350) fundamental value – how a lot it prices per chip to seize 1,000 models. Normally that may translate pretty intently to the precise retail price to us customers, with possibly a $20 premium on high. With the noises round Coffee Lake stock shortages, nonetheless, I would not be stunned to seek out the Core i7 8700Ok to be knocking across the $400 mark.

Intel Core i7 8700Ok specs
These Intel eighth Gen, Coffee Lake CPUs are those meant to type the bedrock of our gaming rigs for the following yr (give or take a few months) they usually’re a terrific barometer of the processor market circa late 2017. The undeniable fact that Intel are introducing a brand new era of chips lower than a yr after their seventh Gen Kaby Lake CPUs reveals their unwillingness to cede the mainstream market to AMD’s multi-core Ryzen choices. The eighth Gen wasn’t meant to launch now; Intel have pulled in just about each single CPU launch since AMD unveiled their Zen processor structure.
Coffee Lake, represented right here by the six-core i7 8700Ok – the highest processor within the Intel eighth Gen lineup – is a vital response by the chip big to their rivals who massively upped the core-count of their newest processors. But it’s nearly only a non permanent bandage for Intel’s CPU vary whereas they proceed to battle with their principal focus, getting these darned 10nm transistors purposeful, inexpensive, and dependable.
The massive information for the Intel Coffee Lake vary is that that is the primary time they’ve upped the mainstream core-count in practically ten years. The Core i7 8700Ok is their new six-core / 12-thread flagship for the eighth Gen, delivering one other pair of full Intel cores in contrast with the quad-core / eight-thread Core i7 7700K launched in January.
It is, nonetheless, nonetheless basically the identical base structure because the Kaby Lake – and subsequently Skylake – processors we’ve already seen. There are some minor revisions, with a extra mature 14nm manufacturing course of, laughably known as 14nm++, and the additional cache these two further cores convey with them. But on the coronary heart of it is a additional optimisation of the identical getting old Intel Core structure we’ve been utilizing for an excellent few years now.
The clockspeed has each been dropped and boosted by way of the bottom clock and Turbo frequencies. While the outgoing 7700Ok sported a four.2GHz base, the 8700Ok has a surprisingly low three.7GHz clockspeed out of the field. That’s doesn’t inform the entire story, nonetheless, as the utmost Turbo frequency has been boosted from four.5GHz on the highest Kaby Lake core to four.7GHz. Those are solely the utmost speeds you’ll see when a single core is harassed versus what you’ll see by way of all-core speeds.
It breaks down so the CPU’s dual-core max pace is four.6GHz, the quad-core is four.4GHz, and in our MSI Z370 Pro Carbon we had the 8700Ok sitting fairly at a normal four.3GHz once we had been pushing all of its six cores to their limits.
Elsewhere it’s just about the identical story as with Kaby Lake. We’re nonetheless speaking about the identical 16 lanes of PCIe three.zero assist from the CPU itself, with an additional 24 on provide from the Z370 chipset, and the identical LGA 1151 CPU socket. Well… kinda.
The Z370 chipset does use the identical socket as Kaby Lake and Skylake’s Z270 and Z170 chipsets respectively however there’s no inter-compatibility between them. You can’t but purchase a Coffee Lake CPU and drop it into your present 200- or 100-series motherboard, or vice versa. On the floor that looks as if an arbitrary, synthetic restriction put in place by the chip maker to drive folks into an pointless improve. But, in actuality, I believe it was an absolute necessity as a result of Coffee Lake had to beat Ryzen.
The new socket has been designed particularly to ship the additional energy these six-core CPUs demand over the outdated quad-core design. A fast take a look at the TDP ranking of 91W vs. 95W between the Kaby and Coffee Lake processor might need you performing an incredulous spit-take, however this further energy was by no means in regards to the inventory efficiency of the relative CPU generations, it’s all about overclocking.
The authentic Coffee Lake engineering samples had been examined utilizing the Kaby Lake chipset, which might point out the brand new processors may nonetheless run on a Z270 board if Intel wished to. But if I had been a betting man I’d gamble Z270 wouldn’t be able to delivering the overclocking efficiency the Coffee Lake processors must so as to match AMD’s eight-core and six-core Ryzens. The 8700Ok wants all that improved, constant energy supply the Z370 is pushing its means.
If Intel hadn’t created the overclocking assist for Coffee Lake they might characterize nothing greater than a six-core model of Kaby Lake. That would in all probability not be sufficient to persuade folks the Core i7 8700Ok was nonetheless price a glance within the face of the cheaper Ryzen 5 1600X and its six-core / 12-thread configuration. At least with the 300-series chipset they’ve received extra critical overclocking chops to supply too.
It’s nonetheless relatively galling that the non-Ok-series, and decrease core-count, elements stay incompatible with the last-gen chipsets. But I suppose as soon as Intel had made the choice to restrict one a part of the Coffee Lake puzzle to the Z370 they needed to follow their weapons and refuse entry to the opposite chips too.
It’s all going to be completely different now, with Intel delivery a hexcore CPU within the mainstream market, it’s going to make all their outdated Core i7 quad-core / eight-thread chips look totally laggard, proper? Yeah, you see the place I’m going…
If nothing else, the 8700Ok is capably highlighting precisely how a lot distinction having six cores over 4 cores really makes with regards to gaming. Practically none. Put cheek-by-jowl with a Kaby Lake 7700Ok – itself hardly a revolutionary chip – there’s nearly nothing to decide on between them. In reality, at inventory settings we really see a few situations the place the higher-clocked Kaby Lake CPU delivers a number of further frames per second.
I – foolishly, it seems – thought the DirectX-12-based Hitman and Rise of the Tomb Raider may ship some efficiency differential due to the additional cores, however neither they, nor the Vulkan-powered model of Doom, may provide any multi-core succour.
The solely recreation that basically reveals any real profit from the additional Coffee Lake cores is the DX12 model of Civilization VI. This is recreation which greedily gulps down as a lot CPU energy as you may feed it. While the efficiency of the opposite titles in our benchmarks is much extra reliant on the pixel-pushing prowess of your graphics card, Civ VI takes full benefit of each little bit of hardware it’s important to provide it.
So, so far as Intel’s claims about it being the being their greatest gaming CPU go, it’s a little bit of a stretch. Civ’s elevated efficiency isn’t actually sufficient to make us go weak on the knees over the potential body fee will increase it may provide. Certainly anybody sitting on a 14nm i7 has no motive to be nervous.
There is, in fact, nonetheless Intel’s newest buzzword: mega-tasking. Can you are feeling that acid style burning in the back of your throat? Yeah, that’s mega-tasking. Makes me wish to rip out my very own intestines so I’ve received one thing to loop over the rafters and string me up as soon as I kick away the stool.
Anyways, mega-tasking is the abhorrent time period Intel use to imply gaming, recording, and streaming on the similar time. For the ultra-niche that doubtlessly makes the additional 4 threads of the 8700Ok a extra fascinating prospect than the outdated 7700Ok was. Maybe not as fascinating as AMD’s $100 cheaper, nonetheless six-core / 12-thread Ryzen 5, or an equivalently priced eight-core / 16-thread Ryzen 7, although. Not at inventory clockspeeds a minimum of.
Ah sure, Ryzen. The 1600X has the identical core configuration because the dearer Core i7 however Intel’s historic per-core gaming efficiency continues to be in proof with Coffee Lake. But it’s attending to the purpose, with elevated DirectX 12 assist from trendy video games, the place there isn’t such an enormous distinction between the Intel and AMD gaming outcomes any extra. Certainly not when there’s a fairly hefty value differential between them.
On the straight CPU efficiency metrics, nonetheless, Intel’s new chip has much more going for it. Its inventory efficiency is properly prematurely of the AMD processor’s most overclocking outcomes, with the Cinebench rendering and X264 video encoding exams highlighting the place the Intel structure has received the products. It’s the identical story wanting on the compression and extraction figures too, with the 8700Ok taking a 3rd much less time to compress a 5GB folder of blended media and 13% faster at extracting the identical factor.
And once you throw within the mouth-watering overclocking efficiency of the Coffee Lake chip you get efficiency that bests even the $400 (£366) Ryzen 7 1800X. And that’s why Intel needed to get the height overclocking efficiency into the brand new platform, and needed to lock out any hope of getting a Coffee Lake CPU operating in a 200-series motherboard. They wanted the additional energy as a result of they had to beat Ryzen.
Intel’s Coffee Lake lineup has been created with a really clear goal: beat AMD’s Ryzen processors and do it rapidly. To that finish they’ve pulled within the launch date of this eighth era of their Core structure in order that they arrive earlier than the top of the yr and have lastly delivered the primary Intel hexcore to the mainstream finish of the market. But whereas they’ve succeeded of their key aims, that’s each a boon and a detriment to the Core i7 8700Ok.
The six-core / 12-thread i7 is able to outperforming the most effective eight-core / 16-thread AMD’s Ryzen 7 can provide, when you pull some overclocking shenanigans. The cheaper Core i5 8600Ok does the identical job on the Ryzen 5 1600X, regardless of having half the thread-count. That’s all nice, however it has come at the price of cross-generational compatibility.
It’s doubtless this must greatest Ryzen, in any respect prices, which has resulted within the newest chips not being appropriate with the 200-series boards that launched at first of the yr. Because they wanted that overclocking efficiency Intel required a brand new chipset able to delivering sufficient energy to get these further cores properly over 5GHz.
It additionally means we’re basically a stop-gap answer, one other 14nm ‘optimisation’ on the best way to potential octacore CPUs subsequent yr sitting in a brand new Z390 chipset. As Intel’s functionality to ship constant die-shrinks is on the decline, the speed at which top-end chips are being changed appears to be quickly rising. The i7 8700Ok has arrived, cannibalising the seventh Gen processors in each commonplace and Core X-series trim.
I’d really feel dangerous for Kaby Lake, solely allowed ten months of life, if it didn’t characterize such an totally uninspiring set of CPUs. I do really feel a lot worse for the Skylake-X mayfly, the Core i7 7800X, which lasted a scant three months within the wild earlier than being castrated by its makers, and most of all I really feel for anybody who spent precise cash on getting that chip into their X299 rig. I don’t really feel sorry for any of the mugs who purchased both the i7 7740X or i5 7640X, nonetheless, they deserve every little thing they get… apart from sympathy.
But what does this spectacular Coffee Lake core improve imply for players? Almost nothing. Only Civ VI delivers any efficiency enhance over the Kaby Lake i7, exhibiting as soon as extra how little relevance an elevated thread-count has for many players. The i7, then, is overkill for us, extra so than with any earlier Intel era. It’s additionally more likely to relatively costly with international inventory shortages more likely to artificially inflate the value of the whole Coffee Lake vary.
But nonetheless, the actual fact stays that your new Coffee Lake i5 is ready to ship greater than sufficient efficiency for our gaming wants, in order that’s the place the good cash goes.
